What is tap off unit electrical?

What is tap off unit electrical?

Tap-off boxes are used to draw power from the busduct. The tap-off boxes have a special plug head (mast) which inserts into the busway track slot. Twist the tap-off box 90 degrees to make electrical connection. The blades in the mast fit into the busbar channel inside the busway track for a compression connection.

What is an electrical bus duct?

Bus duct is used in commercial and industrial settings to conduct electricity to power cables or cable bus. Structurally, a bus duct is a sheet metal duct containing either aluminum or copper busbars (metallic strips or bars that conduct a substantial electrical current) in a grounded metal enclosure.

What is tap off point?

Definitions (f) “tap off point (TOP)” means a facility on the pipeline from where the petroleum products are diverted in to a delivery terminal or into a spur line or another pipeline which may also be called the intermediate delivery station.

What is cable busway?

Cable Busway is a flexibe cable bus duct power distribution system that provides a high degree of reliability and efficiency in both low amperage and high amperage applications.

What is spur pipeline?

“spur-line” means a pipeline necessarily originating or branching out from the trunk or transmission pipeline or sub-transmission line or another spur line or from a terminal station on the existing transmission or trunk pipeline with diameter and capacity not greater than the trunk or transmission pipeline but having …

What is pipeline capacity?

Pipeline capacity is the amount of natural gas that can be transported through a pipeline at any given time. That seems simple enough, but capacity can take on several different variations.

What is a busway riser?

Busway risers (vertical busway) can be installed economically in a high-rise building where it can be used to distribute lighting and air conditioning loads. Busway is used in various applications and can be found in industrial installations as well as high-rise buildings.

How do you calculate the capacity of a gas pipeline?

1: (1) Compute CFM demand for all appliances Maximum gas demand of outlet A: 32 cubic feet per hour (from Table 1). 35,000BTU/1,100 BTU2 = 32 Maximum gas demand of outlet B: 3000/1,100 = 3 3 cubic feet per hour (from Table 1). 65,000/1,100 = 59 Maximum gas demand of outlet C: 59 cubic feet per hour (from Table 1).

How is a pipeline capacity determined?

Pipeline capacity is also measured in different units. In the United States, the standard measure is dekatherms, but operators also express capacity in terms of cubic feet. In order to convert dekatherms to cubic feet, one must know the average heating (btu) value of the gas.

What is the purpose of busbar?

A busbar is an electrical junction used for collecting electric power from the incoming feeders and distributes them to the outgoing feeders. The main purpose of a busbar is to carry electricity and distribute it. Busbars are used to make the systems more efficient.
